The evolution of gene regulation underlies the morphological divergence of two closely related Drosophila species. Cell. 2008; 132 :783–793.Jeong S, Rebeiz M, Andolfatto P, Werner T, True J. Carroll SB. The evolution of gene regulation underlies a morphological difference between two Drosophila...
What is the difference between an allele and a trait? An allele is a specific version of a gene, while a trait is an observable characteristic influenced by alleles and environment. 15 What is a recessive allele? A recessive allele is one whose effects on the phenotype are masked by a dom...
each gene resides at a specific locus (location on a chromosome) in two copies, one copy of the gene inherited from each parent, namelymale parent and female parent. The copies, however, are not necessarily the same. When the copies of a gene differ from each other, they are known...
What is the difference between the mechanisms of transcription and replication of DNA? Distinguish the differences between alleles, phenotype, character, and trait. A horse has 64 chromosomes and a donkey has 62 chromosomes. A cross between a female horse and a male donkey produces a mule. ...
What is the difference between a desmid and a diatom ? What is the difference between DNA, chromosomes and genes? What are the differences between Michaelis and allosteric enzyme? Distinguish the differences between alleles, phenotype, character, and trait. What are the differences between Lithostra...

There were no significant differences in the area covered by Alz-50 or in the proportion of Alz-50-stained neurons in the nucleus basalis of Meynert of Alzheimer's disease (AD) patients with one or two ApoE epsilon4 alleles as compared with those without any ApoE e4 allele. However, ...
AIM To investigate the existing difference between cagA and cagM in cag Ⅰ of Helicobacter pylori (H. pylori) isolated from Chinese patients. METHODS Fragments to cagA and cagM in cag Ⅰ was amplified by polymerase chain reaction(PCR) in 107 H. pylori strains from Chinese patients. RESULTS ...
and the interplay between genes and the environment. Trait and character are two terms used in genetics interchangeably to describe features of organisms. A combination of two traits occurs in an organism and they can be either inherited or determinedAs an example, the blue eye color is a trait...
Genes common to both sex chromosomes and therefore present in two copies in both females and males. Skewing of X chromosome inactivation When the process of X chromosome inactivation selects for or against alleles on the active X chromosome. This nonrandom pattern of inactivation results in overre...
